CAR-COUPLING.

SPECIFICATION forming part of Letters Patent No. 397,375, dated February 5, 1889.

Application filed July 28, 1888. Serial No. 281,325. (No model.)

To all whom it may concern.-

Be it known that I, HORACE I]; MANSFIELD, of Boston, inv the county of Suffolk and State of hlassaclnisetts, have invented certain new and useful Improvements in Car-Couplers, of which the following is a full, clear, and exact description.

This invention consists of a coupling for steaina-ailroad cars constructed and arranged for operatioi'i all substantially as hereinafter fully described,reference being had to the accompanying sheet of drawings, in which Figure 1 represents in vertical longitudinal central section the draw-heads of two cars coupled together in accordance with this invention. Fig. 2 is an end elevation of a car having this car-coupling applied thereto; Fig. 3, a plan view of the draw-head at the right in Fig. 1; and Fig. 4: is a horizontal section on line 1 i, Fig. 1.

In the drawings, A 13 represent, respectively, two dran heads in detail section of two steamrailroad cars, each having the usual opening, 0, for the insertion of the link D, each drawhead being secured to its respective draw-bar in any of the usual ways, but not shown in the drawings.

E is the link-pin, having cross-arms F at its upper end and an eye, G, to which eye is secured the end of a chain or cord, H. This link-pinis arranged to freely fit within a central vertical socket, K, in the upper part, a, and lower part, Z), of each d raw-head, as shown in the draw-head A, Fig. 1, and to also freely fit a socket, J, in the two parts a and b in each draw-head in the same vertical plane with the socket K, as shown in Fig. 1.

The socket J in the upper part of each drawhead is elongated longitudinally, as shown, and somewhat so in the lower part, b, and on each side thereof, on the upper part of the drawhead, is an upright rib or extension, L, the upper edge, 9, of each of which extends backward in an upwardly-inelined angle of, preferably, about forth-five degrees, and having a hook or stop, M, as shown in Fig. 1.

The chain or cord 11, attached to pin E, extends back and upward, passing through an eye, N, secured in the end of the car, and from thence to the top of the car, where its other end is attached to a rod or handle, P, arranged to slide in a guide, 71,01 the car, and attached to this chain or cord above the eye N and extending to each side of the car are chains or cords Q R, each having a handle, S, for operation of the same, arranged to slide respectively in a guide, on, on the car, as shown in Fig. 2.

The operation of the coupler is as follows: The link I) and the pin E are first placed, as shown, in the draw-head A of one car, the pin being in the socket K, the link then projecting by its end a from the draw-head suffieiently and in a horizontal position for such end as the other car to be coupled thereto appreaches to enter its draw-head opening, which has its pin in its highest position, (shown in. dotted lines, 1,) .it having been moved up to such position by pulling upon either one of its chains or cords, its cross-arms sliding upon the inclined edges 9 and abutting against the stops M, where the pin is held, and W116 n the end a of the link has entered the draw-head sufficiently the chain is released and the pin by its cross arms slides down the inclined edges, its lower end entering the opening in the link and the socket J in the lower part of the. draw-head, which couples the cars, as shown in Fig. 1.

The chains or cords obviate the necessity of going or reaching between the two cars to couple or uncouple them, and to uncouple the cars pull upon either one of the chains or cords of either car, which will raise its pin and leave the link free to draw out of its draw-head.

The upper face, '1, of the bottom part, Z), of each draw-head inclines downwardly from the inner end of the opening 0 to the outer end, which outer end is rounded off, as at r, 1, for the entrance of the link therein.

The pin is square in crosssecti.on, as shown in Fig. 4-, to prevent its turning in its socket, so that the cross-arms F will always be across the draw-head and inclined edges, the back side, to, of the pin beiu g round to it the end of the link.

All the parts can be made of any suitable metal and of any suitable size and shape.

Having thus described my invention, what I claim is- 1. The combination, with a draw-head of a car having an opening, 0, a socket, J, and inclined edges g at the sides of said socket, of a pin, E, provided with cross-arms F, for the purpose specified.

2. The combination, with a draw-head of a car having an opening, 0, a socket, J, inclined edges g, and a stop or hook, M, at the sides of said socket, of a pin, 1, provided with crossarms F, for the purpose specified.

3. The combination, with a draw-head of. a car having an opening, U, a socket, J, and inclined edges 9 at the sides of said socket, of a pin, E, provided with cross-arms E and connected by chains or cords II Q R to the 0nd of the car, for the purpose specified.

i. The combination, with a draw-head of a car having an opening, C, a socket, J, inclined edges g at the sides of said socket, and a socket, K, of a pin, E, provided with cross-arms is, for the purpose specified.

0. The combination, with a draw-head of a car having an opening, C, an inclined bottom surface, T, socket J, inclined edges g, and stops or hooks M at the sides of. said socket, of a pin, E, provided with cross-arms 'F, for the purpose specified.

(3. The combination, with a draw-head of a car having an opening,(1, an inclined bottom sin-face, '1, socket J, inclined edges g, stops or hooks M, and socket K, of a pin, E, provided with cross-arms F, for the purpose specified.

In testimony whereof I have hereunto set my hand in the presence of: two subscribing witnesses.
